No, Your Furnace Should NOT Be Blowing Cool Air

Fortunately, we live in Georgia, which means that winters around here aren’t anything compared to those up North. But, even so, you installed your furnace for a reason: to keep you warm! So, of course, if your system suddenly starts blowing cool air, it’s definitely a cause for concern.

But do not fret! You’ve come to the right spot. See, there are plenty of reasons why your furnace might be blowing cool air, and below, we have outlined some of them for you. All you have to do is keep reading to find out more ( and yes, remember to call our team when you need furnace repair in Snellville, GA!)

So, Where’d the Heat Go?

There are a number of issues that can cause your furnace to start acting more like your air conditioner:

Thermostat Troubles

Sometimes the problem isn’t with the furnace itself, but rather with the thermostat. If your thermostat is malfunctioning, it might be misreading indoor temperatures or it might not be properly regulating the temperature in the furnace.

We also recommend checking your thermostat to see if its set to “AUTO” rather than “ON.” When it is set to “ON,” the fan will blow continuously, even if the furnace isn’t actually heating the air.

A Clogged Air Filter

A clogged air filter can cause significant problems if ignored, one of which is a lack of heat. A dirty air filter restricts airflow into your furnace, causing it to overheat. When this happens, your system will shut down as a safety measure. The fan, however, will continue to blow air to cool down the heat exchanger.  For this reason, we recommend changing out your air filter every 1-3 months during the heating season!

Broken Heating Elements

When any of the elements responsible for heating air are broken, you can expect cool air from your furnace. Fortunately, a certified HVAC professional can inspect each element of your furnace to pinpoint the source of the problem.

A Ductwork Breach

When there is a breach in the ductwork, warm air will leak from the system. In addition, a breach will cause air from other parts of the house, most of it colder than air from the furnace, to enter the system causing a drop in temperature.

Yes, You Need to Call in a Professional

If your furnace is in need of repairs, do not hesitate to call in a certified HVAC professional for help. Only a professional has the tools, training, and expertise to safely and correctly handle the complex needs of your system, the first time around.

And yes, there may be plenty of amateurs willing to service your system for a fairly cheap price, but remember, sometimes an attempt to save money could end up costing you much more in the long run. So trust us when we say, “When it comes to your comfort and your budget, you don’t want to take any risks!”
